Specification of Letters Patent.

Patented Apr. 15, 1913.

Application filed July 25, 1912. Serial No. 711,586.

To all whom t may concern:

Be it known that I, JOHN I). GAGE, a citizen of the United States,resident of Vineland, in the county of Cumberland and Stat-e of NewJersey, have made a certain new and useful Invention in Planes; and Ideclare the following to be a full, clear, and exact description of thesame, such as will enable others skilled in the art to which itappertains to make and use the invention, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

Figure 1 is a central vertical longitudinal section of the invention.Fig. 2 is a detail plan view of the plane stock. Fig. 3 is a detail planview of the cutting plate and the guide clamp. Fig. 4 is a detail planview of the cap iron.

The invention is designed to simplify and improve the carpenters plane,and particularly the block plane, in such wise as to provide advantagesrelating to its durability and useful facilities; and it consists in thenovel construction and vcombinations of parts, as hereinafter set forth.

In the annexed drawings the numeral 2 indicates a plane stock; 3 a capiron; 4 a cutting plate or bit, and 5 a guide clamp which is secured tothe bit.

The plane stock is provided with integral inclined bearings 6 on theupper or inner surface of its bottom, in rear of the transverse slot 7through which the cutting bit is designed to protrude, these bearingscoinciding in their inclination with the beveled bearing 8 of thebottom, which extends to the acute rear margin of the slot. The frontmargin of this slot is formed by a transverse rib 9 which connects theside walls 12, 12, which are substantially parallel and form guides forthe movement of the cap iron and bit. Connecting these walls, in thethroat of the stock, above and in rear of the slot, is a cross bar orbearing 14, which is perforated and threaded for the passage of a strongset screw 15, the axial direction of which is designed to besubstantially in line with that portion of the bottom which is adjacentto the acute edge of the transverse slot. The cutting plate or bit 4 isdesigned to rest on the bearings 6 and 8, and as the setting andsecuring def vices are located above it, this cutting plate can bedisposed at a very low angle, suitable for a plane of the characterindicated.

The cutting plate or bit is provided with the usual series of adjustmentslots, and on the upper surface of this plate is adjusted and securedt-he holding or guiding clamp 5, which consists of a longitudinal baseportion 16 and an upward projection or lug 17 which is provided with abearing recess 18, open at its upper end and provided with an open-topslot bearing in rear to receive the neck of an adjusting screw 19. rIhebase of the holding clamp is provided with a threaded aperture for aclamp screw, extending through a slot of the cutter plate. The base ofthis clamp 5 has parallel sides, and it is designed to engage and slidein a parallel-side recess 20 in the bottom of the cap iron 3. The bottomof the cap iron is plane to fit neatly the top of the bit, at the sidesof the clamp lug. The top of the cap iron is made with a beveled frontwall 21, a sloping angular bearing 22 in rear of the top of this frontwall and lateral bearings or lugs 13 in line with each other anddesigned to engage the transverse bar 14 of the plane stock when the capiron is forced into position. The cap iron is provided with a middleopening or slot 23 for the reception of the clamp lug, and in rear ofthis opening is provided a transverse bear-- ing 24 in which is made athreaded opening for engagement with the adjusting screw 19.

The shouldered end of this adjusting screw engages neatly the bearingrecess 18 of the clamp lug 5, so that the adjustment of this screw movesthe clamp and cutter plate backward or forward with reference `to thecap iron, which therefore forms the principal or purchase element forthis adjustment.

In a plane of this character the cap iron is designed to be providedwith a bowed handle portion or push bearing 25 of suffi cient height andspan to protect the adjustf ing screw and allow removal of the cutterand clamp.

The front of the cap iron is of proper height to pass easily under thetransverse bar or bearing 14 of the stock. And when the cutting plate,properly and` securely fastened to its guide clamp, is provided with itscap iron in engagement with the adjusting screw, a combination of partsis formed which is designed to be placed on the bottom inclines of thestock and, if the set screw 15 is raised, will easily slide forward toposition. In normal position the bearings 13 of the cap iron abutagainst the bar 14 of the stock, and the sloping bearing 22 lies underthis bar. The screw 15 being now set down firmly against this slopingbearing, operates to drive the cap iron forcibly7 home against thetransverse bar or bearing 14, and to clamp the cap iron firmly in placeon the cutter plate. Adjustment of the bit is easily effected by meansof the adjusting screw of the cap iron.

This plane is designed to be in a manner self-setting as its capV ironand plane iron fit together accurately beforehand, and when simply laidin place will slide forward to true position. I/Vhen the cutting plateis properly secured to its guide clamp, no adjustment of the holding orsetting parts is required, except in regard to the operation of the setscrew and the adjusting screw. The simple devices of this plane can betaken apart and put together exactly as they were in a few seconds.

The setting and holding devices of the plane are placed above thecutting plate, in such wise that the latter may be arranged at as low anangle as may be required. The cap and plane iron are forced .to accurateposition and held therein by a single set screw, and without other careand attention than is required to turn the screw forcibly home.

In taking out the bit and cap iron no movement of the adjusting .screwis required. The set screw being loosened up sufficiently, the cap iron,guide clamp and cutting plate will .slide back and, without moving theadjusting screw, the cap iron can be lifted from the cutter plate. Uponreplacing the parts without adjustment of the screw of the cap iron, thebit takes its former position with relation to the cap iron accurately,so that when placed in the stock the cap iron will take normal positiontherein and there will be no change in its shaving adjustment.I It isdesigned to provide'in this plane practical operating parts which willwhen once adjusted always go together in accurate and true position withrelation to each other to secure the same thickness of shaving withoutfurther operation of means of adjustment.
